Materiales y métodos: Estudio observacional, transversal y analítico consistente en la toma de muestras sanguíneas para determinar y comparar las concentraciones de 25-hidroxivitamina D. El tamaño de la muestra se determinó previamente con base en una prevalencia de 35% para la deficiencia de vitamina D, un error alfa de 0.05 y un error beta de 0.80.  Resultados: Se reclutaron 784 embarazadas, 394 con diabetes gestacional y 390 sin este padecimiento. En este último grupo 51% (n = 199) tuvieron concentraciones suficientes, 33% (n = 129) concentraciones insuficientes y 16% (n = 62) concentraciones deficientes. En el grupo de mujeres con diabetes gestacional, 12% (n = 47) tuvieron concentraciones suficientes, 67% (n = 264) concentraciones insuficientes y 21% (n = 83) concentraciones deficientes. Los resultados obtenidos muestran que 88.9% (n = 350) de las mujeres con diabetes gestacional tenían concentraciones inferiores a 30 ng/mL vs 48.5% (n = 189) del grupo sin diabetes gestacional (p &lt; 0.00001; RM: 7.69; IC95%: 5.3-11).  Conclusiones: Las concentraciones inferiores a 30 ng/mL de vitamina D total son más frecuentes en pacientes con diabetes gestacional.]]></p></abstract>

Materials and methods: Analytical cross-sectional study that consisted in taking blood samples to determine and compare the concentrations of (25[OH]D) vitamin D. The sample size was previously determined considering a prevalence of 35% for vitamin D deficiency, an alpha error of 0.05 and a beta error of 0.80 for which 784 pregnant women were recruited, 394 patients with gestational diabetes and 390 without gestational diabetes.  Results: In the group of patients without gestational diabetes, 51% (n = 199) had sufficient levels, 33% (n = 129) insufficient levels and 16% (n = 62) deficient levels. In the group of patients with gestational diabetes, 12% (n = 47) had sufficient levels, 67% (n = 264) insufficient levels and 21% (n = 83) deficient levels. The results obtained show that 88.9% (n = 350) of women with gestational diabetes present with levels lower than 30 ng/mL vs 48.5% (n = 189) of the group without gestational diabetes [p &lt;0.00001 OR 7.69 (IC95%: 5.3 - 11)].  Conclusions: Levels below 30 ng/mL of total vitamin D are more frequent in patients with gestational diabetes.]]></p></abstract>
